Determines whether the query executes as a single native MERGE statement.

The native MERGE statement can only be used when the condition targets the merge table itself and when there is something to insert. In all other cases the generic SELECT + INSERT/UPDATE emulation is used.

Return value

bool TRUE if the query executes as a native MERGE statement, FALSE if it uses the generic emulation.
